Mark Zuckerberg has done his very first live Q&A as a way of promoting Facebook Live. During the hour-long section, which has been viewed by over 7.5 million people, the CEO discussed a wide range of subjects, including telepathically sharing thoughts on Facebook, whether his social network would ever charge people for using it, and rumors that he’s a gigantic lizard disguised as a human.

Being the internet, one of the first questions Zuckerberg faced was: “Mark, are the allegations true that you’re secretly a lizard?” Tackling the remark with the kind of sense of humor CEOs are known for, he replied: “I’m gonna have to go with ‘no’ on that. I am not a lizard. But keep the high-quality comments coming in please, this is surely on track to be a great Live Q&A if we continue getting stuff at that level of quality.”

Possibly realizing that he sounded a bit irritated, Zuckerberg added: “there’s actually a lot of funny stuff in here, too,” though he didn’t address any of it.

Away from the subject of lizard overlords, Zuckerberg spoke about what he'd previously referred to as “the future of communication”: telepathy. He said that as online sharing has evolved from text to photo to video and to live video, the next step will be virtual reality; a feature Facebook showed off in April.

But what comes after VR? According to Zuckerberg, it will be the ability to share thoughts directly from our brains using technology. But he did admit that this was “decades away.”

"You know that’s obviously pretty far-off. There are a lot of technology advances that are going to need to happen for that to be something safe to use, and something you’d actually want to do and all that," he said. "But I do think in the future we will have the ability to just capture kind of a raw emotion or thought that we have, when you want and how you want, and of course it’s really important that people have the power to do this in the way that they want to be able to share that with other people."

Annoying spam posts that claim Facebook will eventually charge for its services have plagued the social network for years. When questioned if the site would remain free, Zuckerberg confirmed that it will never ask users to pay anything, as it continues to be “ad-supported.”

At around 45 minutes, Zuckerberg brought in a special guest: Jerry Seinfeld. The comedian was in the building for an Oculus demonstration and to perform his own Facebook Live Q&A.

The slight awkwardness between the two suggests a Zuckerberg/Seinfeld comedy act wouldn’t be very successful, but it did allow the CEO to talk about his daily routine, his fitness regime, and the broken arm he suffered when falling off his new bike. Zuckerberg told Seinfeld that as it has no cast, “people don’t know what to do with a broken arm that doesn’t quite look broken.” He added: “My wife wants me to put a temporary tattoo on it saying ‘broken’.”

On the whole, the Facebook Live Q&A was well-received, and Zuckerberg said he planned to do more in the future, though he warned users not to expect “such interesting guests.”
